Dear "Titivillus Foundry", font owner.
I have just found that, there is a Thai fashion garment Company name, "ISSUE" by Mister "Roj". He is using your font for Commercial use for more than 10 years ago. Till now the company is one of the top ten Thai-International fashion brand in the country. In my opinion, I think you are deserved some return from him, as well.

P.S.
I am an Architect who was stolen my own work by him.
And I found your font during the time of making his Company Signage.
